Ohio, a corporation of Maryland Application September 5, 1935, Serial No. 39,210 In Germany November 17, 1934 7 Claims.

The invention relates to cash registers and accounting machines provided with a printing device having several printing places at which during a machine operation two different record materials, as for instance, a pass-book and a ledger card, can successively be imprinted. Such a machine is shown and described in the United States Letters Patent No. 1,628,336 to B. M. Shipley to which reference may be had for a detailed description.

It often happens that, for some reason, the pass-book is not available when the original entries are made and, under these circumstances, a record is made on a receipt instead of in the passbook. As a result of this, supplementary entries must often be made in the pass-books, and, in these supplementary entering operations, the second printing operation must be eliminated in order that a record, which could ordinarily be made by such an operation, may not be made and used for an improper purpose.

Thus, the main object of the invention is to adapt a printing hammer actuating mechanism which normally effects several successive impressions in a machine operation so that it will perform a single stroke in each subsequent supplementary entering operation.

Another object of the invention is to provide printing hammer control means adapted to be actuated after the first hammer stroke by a special key depressed in an adding operation and by the total lever displaced in a subsequent total taking or balancing operation.

Further object of the invention will be pointed out in the following detailed description with reference to the annexed drawings.

A preferred form of an embodiment of the invention is shown in the annexed drawings.

Of said drawings:

Fig, 2 is a. front view of a rack controlled by the differential device of said special key bank,

Fig. 3 is a side view of the shifting means for the actuating cam disk of the printing hammer,

Fig. 4 is a front view of the printing hammer and its actuator,

Fig. 5 is a side view of the total lever and means connected therewith.

A machine of this type as referred to, is preferably provided with several banks of special keys. Of said banks the first serves to classify and subdivide the deposits, the second the withdrawals, and the third for balancing actions. In the first mentioned two banks one key is provided for supplementary transactions. For each special key bank a differential device is arranged which is well known in the art and is also shown and described in the beforementioned Shipley Patent No. 1,628,336. It consists of a driving segment I (Fig. 1) which is given first a counterclockwise and then a clockwise movement in every operation. This segment is actuated by a pair of cams 2 fast on the main drive shaft 25. The cams transmit their movement to the segment by means of a Y-shaped member 4 and a link 5, as it is well known in the art. Normally latched to the segment I is a differentially movable member II, which is moved by the segment I on its clockwise movement. The differential member I I is arrested and unlatched from the driving segment I when the latch engages a depressed key.

Pivoted to the difierential member I I is a beam I3 the bifurcated end of which cooperates with a roller I 4 on a link I5 for moving the link and roller differentially. At its lower end the link I5 is connected by an arm I! to a spiral segment I8 loose on a rod IS. The segment I8 meshes with a spiral pinion I9 secured to a shaft 20 which carries a toothed segment 2| (see also Fig. 2).- The segment 2| meshes with a rack 23 guided by and on two fixed rollers 22. A projection 24 is provided on the extreme left end of each of the two racks 23 allotted to the special keys for deposit and withdrawal transactions. The projections 24 cooperate (see also Fig. 3) with a lever 26 loosely mounted on a shaft 25. The rack 23 allotted to the third special key bank has no projection 24 because the old balances are printed merely upon the audit strip but not upon the inserted record materials.

The lever 26 is provided with a bent-over portion 21 which lies over an arm 28. The arm 28 is pivoted at 29 (Fig. 3) to a pitman 39 which is guided by a stud 3I and by its bifurcated end on the main shaft 32. A projection of the arm 28 is connected by means of a spring 33 to the pitman 30. The spring 33 tends to rotate the arm 28 counter-clockwise (Fig. 3) and the lever 26 clockwise (Fig. 2). A roller 34 on the pitman 30 projects into the cam groove 35 of a gear 36. As the gear 36 makes a full revolution at each machine operation, the pitman 30 is shifted to the left once at each machine operation, and returned thereafter into the position shown in Fig. 3. The arm 28 partakes in this movement.

A pin 31 provided on a shiftable shaft 38 having secured thereto a bifurcated arm 39 (Fig. 4), extends into the path of the arm 28. The arm 39 engages an annular groove in the hub of a cam disk 4| shiftably, but not rotatabli arranged upon the printer shaft 40, which disk has thereon a narrow cam 51 and a broader cam 58. The cam disk ll cooperates with the roller 42 of a bell crank lever 55 fast to a shaft 44, by which lever the drive of the printing hammers 45 is effected. The printing hammers 55, the platens 46 of which cooperate with the type wheels 418, are rockably mounted upon a shaft 45. Beside each printing hammer l a' a bell crank lever 51 is arranged, the arm 48 of which engages, under the action of the spring 89 attached toits other arm 58, a pin 5| of the appertaining printing hammer 45. A projection 5!!! of the lever 57 bears under the action of the spring 59 upon a bail 52, the one arm of which carries a pin 54 on a projection 53. The pin 54 engages a curved slot 55 of a member 56, the left end of which is linked to an arm of the bell crank lever 43.

When the cam disk l! is positioned as outlined in Fig. 3, the narrow cam 5'! is out of the path of the roller 42, which then will be actuated by the cam 58 only. During the counter-clockwise rotation of the shaft 58 in a machine operation, the cam. 58 (Fig. 4), by means of the lever 43, rocks the member 56 to the left and by the pin 54 rocks the bail 5 2. Rocking the bail 52 tensions the spring 19 by means of the lever 'l. Thereupon the arm 58 f the lever}?! frees the pin and the printing hammer 45 is lowered clockwise under the action of its own weight. When the cam 58 has left the roller 52, the spring 59 becomes effective and rocks, suddenly, the lever 41 counter-clockwise the arm 58 of which raises, by means of the pin 5!, the printing hammer 55, and its platen 55 presses the inserted record material against'the type wheels 41!] arranged above an ink ribbon.

7 Normally, during a machine operation the shaft 38 is shifted to the right and the cam 51 is moved into the plane of the roller 42, so that a second hammer stroke is effected thereby. The shaft 387is shifted to the right in the following manner:-= 7

At the start of a machine operation, the pitman 30 is moved to the left by the curved groove '35. Thereupon the plane surface 59 of the arm 28 slides alongrbeneath the pin 31, till its recess 88 is below' the pin 31. When the racks 23 are moved into a position where-in no projection 24 is beneath the free end of lever 26,

' the bent-over portion 21 of the lever 25 takes an ineffective position, and the arm 28 can rock counterclockwise under the action of the spring 33 till its recess 58 engages with the pin 37, and at the same time its pin 6i disengages a locking pawl 62 pivoted to the frame. In this manner the shaft 38 is coupled with the pitman 3|]. ,In, the course of the counter-clockwise move: ment of the gear 35 the pitman 35 is moved again to theright by the cam groove 85. Thereupon the shaft 38 is shifted and the cam 5'! is moved into the path of the roller 42. The parts remain inthis position, till the pitman 38 is shifted to the left at the beginning of the next machine operation. 7

When, however, the differential device of the special key bank for deposit and withdrawal is set by the supplemental operation key, the appertaining rack 23 has moved the projection 24 below the lever. 25 and rocked the latter counter-clockwise (Fig. 2). The bent-over portion 21 of the bail 25 engages a projection 54 of ,the arm .28 and moves it against the action of the spring 33 into ineffective position. The lever 26 is freed of the projection 24 only, after,

at the beginning of a machine operation, the cam groove 35 has moved the pitman 38 and the shaft 38 into the left-hand position (Fig. 3). Simultaneously with the disengaging of the lever 28, the locking pawl 52 resumes its normal position under the action of its spring 55 and arrests the shaft 38 in a position, in which the cam disk 5'1 is out of the plane of the roller 42. When now the pitman 30 is again moved to the right, the lever 28 is held by means of the bent-over portion in ineffective position, so that the straight surface 59 of the lever 28 arrives again below the pin 31, and the shaft 35 remains in the position, in which it is arrested by means of the locking pawl 82. During this machine operation the printing hammer %5 takes only one impression.

The end 56 of a slide 5'! guided by its vertical slot on a rigid pin it and linked at its upper end to an arm 12 rotatable, upon a shaft ll, bears from above under the action of a spring 68 against the bent-over portion 21, of the lever 25. The arm 12 is connected to an indicating device 13, the data of which, visible through a Window 74 of the machine cabinet 15, indicate to the machine operator whether the printing hammer 45 performs one or two printing strokes. The slide 51 carries a pin 16, which cooperates with a locking member 18 rockably arranged on a shaft TI. The locking member 18 has a pin 88 thereon to which a spring 79 is connected and urges the pin 85 against a bell crank lever 8| secured to the shaft H, which lever normally arrests the locking member 78 in its ineffective position, Secured to the shaft fl is also an arm 82 (Fig. 5) the roller 83 of which engages a curved slot 84 of an arm 85 pivoted at 85. The arm 86 is connected by means of, a spring 87 and a pin 88 to a member 89, the roller 90 of which is guided in the cam slot 9| of the total lever 92. When the total lever 92 is moved out of the adding position, the member 89 and the arm 86; are rocked counter-clockwise by the cam slot 9|, and the arm 82 and the shaft 11 clockwise by the curved slot 84 (Fig. 5, compare also Fig. 3). I8 is moved above the pin andarrests the slide 6'! in the position shown in. Fig. 3. Also the arm 28 is held disengaged by the bent-over portion 21 of the lever 26, although the nose 24 is moved out of the path of the lever 25 during the machine operation.

From the arrangement disclosed, it results that the single print is maintained for a total taking operation subsequent to the entering of an amount, at which a printing mechanism has been controlled for single print. When at the end of a total taking operation,.during Which'the projections 24 were moved out of the path of the lever 25, the total lever 92: is restored to adding position, the locking member 18 frees the pin 16, so that the slide 67, under the action of the spring .68, is returned into its inoperative position.

If, during entering .operations, .no projection 24 is positioned beneath the lever 26, thearm 28 rises and carries slide 6'! into its upper position, and, during themachine operation, the

arm 28 shifts the shaft 38 into its two-print.

position, where these parts remain at the end of the machine operation, as before explained. When thetotal lever is moved to total'taking position immediately following such an operation, thelocking member18 is moved beneath the pin 16 and therefore locks the .slide in its Thereby the locking member upper position, and then the arm 28 is under the control of the racks 23. Then, when no projection is beneath the lever 26 during total taking operations, the arm 28 can shift the shaft 38 into the two-print position.

From the above it is clear that the locking member 18 maintains the slide 61 in the position in which it was set during the entering operation that directly precedes a total taking operation, so that the same number of impressions will be made during the subsequent total taking operation.
